GHSA-wwc9-wmm3-2pmf
MEDIUMGHSA-wwc9-wmm3-2pmf is a medium-severity (CVSS 5.4) Cross-site Scripting (XSS) vulnerability in DNN.PLATFORM. O3 Security confirms whether GHSA-wwc9-wmm3-2pmf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
DNN.PLATFORM Allows Stored Cross-Site Scripting (XSS) in Activity Feed
Real-World Exposure
DNN.PLATFORMReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects NuGet packages — download data is not available via public APIs for these ecosystems.
Description
DNN.PLATFORM allows a specially crafted request can inject scripts in the Activity Feed Attachments endpoint which will then render in the feed, resulting in a cross-site scripting attack. This vulnerability is fixed in 10.0.1.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| .NETNuGet | DNN.PLATFORM | ≥ 6.0.0&&< 10.0.1 | 10.0.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for DNN.PLATFORM. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update DNN.PLATFORM to 10.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wwc9-wmm3-2pmf is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-wwc9-wmm3-2pmf is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-wwc9-wmm3-2pmf. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-wwc9-wmm3-2pmf in your dependencies?
O3 detects GHSA-wwc9-wmm3-2pmf across NuGet dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
